Frank Sidebottom was possibly the strangest pop star in history. Jon Ronson, who played in his band, and has co-written a film inspired by the character starring Michael Fassbender, remembers Frank's creator Chris Sievey as being even more eccentric than his papier-mache alter ego

I met Frank—and Chris—a couple of times, and found him—them—charming and fascinating. We won't see the likes of Frank again anytime soon. Very much looking forward to seeing Frank.
